我们使用Dunkl算符方法来构造描述具有内部自由度的N个粒子的一维可积模型。这些模型由一个属于杨氏中心或反射代数的一般哈密顿量来描述,这确保了它们允许相应的对称性。特别地,对于具有自旋的BN型Sutherland模型和推广的BN型非线性薛定谔哈密顿量,对称性的公开问题得到了解答。
We use the Dunkl operator approach to construct one-dimensional integrable models describing N particles with internal degrees of freedom. These models are described by a general Hamiltonian belonging to the centre of the Yangian or the reflection algebra, which ensures that they admit the corresponding symmetry. In particular, the open problem of the symmetry is answered for the BN-type Sutherland model with spin and for a generalized BN-type nonlinear Schrodinger Hamiltonian.
